Figuring them out

  1. How do you figure out key signatures quickly? All those horn people seem to be able to do that.

    two rules of thumb:

    flat keys - the second to last flat is the tonic of the key. 4 flats Bb Eb Ab Db = key of Ab

    Sharp keys - take the last sharp and go up a half step. 5 sharps - F# C# G# D# A# half step up from A# is B.

    easy, dig?
  3. Huh? I just play along and then see what key I'm playing in.
  4. That seems easy enough. This is one of the rare posts that I print out and save :)

    There are other tricks, which are useful if the key centre changes in the song as it does in most jazz tunes.

    So like - the V is the dominant 7th chord in the key so if you see one of these, you can easily work out what the I chord is and hence the key centre.

    Two major 7th chords a fourth apart will tell you that the lower one is the I chord and hence the key!
